Aripiprazole is an atypical antipsychotic medication mainly used in the treatment of schizophrenia, bipolar disorder, and as an adjunct in major depressive disorder. It acts as a partial agonist at dopamine D2 and serotonin 5-HT1A receptors and as an antagonist at 5-HT2A receptors. Aripiprazole is approved and widely used today in many countries.
Pharmacokinetics
Reported pharmacokinetic parameters in healthy adult volunteers after a single oral dose.
